citizen-r ofthe United States, ,residing at Iola,

in the county of; Allena andState of Kansas, have invented certain new and useful Improvementsin;@arpetrSweepers; and I: do declarethe following; to be a full, clear, andexact description: of" the invention, such as will enable otherssk-illed inrtheart to which-it appertains to make and usethe same.

This invention relates to improvements in carpet-sweepers.

The object of the inventionisto provide a carpet-sweeper which willthoroughly sweep, Brush? up and collect the dirt and dust from thefloor or carpet.

The invention consists of certain novelfeatures of construction, combination, and arrangement of parts,.as-will-be hereinafter de+ scribed and claimedi.

In: the. accompanying drawings, Figure '1 is aside view of acarpet-sweep er constructedin accordance with the invention; Fig.2 isa top-planyiewof the same. Fig. 3 isa horizontal sectional view through the casing, showing the interior part in plan. Fig. 4-is a transverse vertical sectional view.

Referring more particularly to the drawings, 1 denotes a box or casingcin which is arranged a transversely-disposed axle or shaft 2, upon the outer ends of which are mounted supporting-wheels 3. The sides of the box or casing 1 are provided with rearwardly-projecting extensions 4, having arranged therein a transversely-disposed shaft 5, on which are mounted rear supporting wheels or rollers 6.

In the lower forward portion of the box or casing 1 is arranged a dust or dirt pan 7. Immediately in rear of the pan 7 is arranged a transversely-disposed rotary brush 8, on the shaft 9 of which, adjacent to each end of the same, are mounted balance or fly wheels 10. The ends of the shaft 9 of the brush 8 project through the sides of the boX or casing and have mounted thereon friction-wheels 12, which are adapted to be 'frictionally engaged by the supporting-wheels 3, whereby motion is imparted to the brush 8. The ends of the shaft 9 are journaled in a bar or strap 13, which passes around the forward end and sides of the casing to which it is secured, the side portions of the strap being spaced from the sides of the casing 1, as shown.

The ends of the axle or shaft 2 of the supporting and drive wheels 3 pass through slots in the sides of the casing and are journaled in by imparting motion to the same.

elongatedbearings-135 inthe bar or strap13-, as shown, so that when'the machineis pushed in a forward direction the wheels 3 will be brought into frictional engagement with the whee s 12 on the rotary brush-shaft 9, there- Atthe end of each forward stroke or eachtime the machine is-stoppedl there will-naturally be a slightrearward movement or jerk, .whichwill throw the supporting-wheel?) forward, thereby disengaging the same from the friction.-- wheels 12, which being-thus released will permit the shaft 9 and brush% to continue to revolve a greater or less number. of turns, owing to the momentum or power stored up by'the fly-wheels-lO on the shaft 9, as will be understood, thereby taking up thoroughly all dirt gatheredby the non-rotary brush 16, hereinafter described.

Secured to the rear. extensions l: of the box or casing 1 are inwardly-projecting vertically-disposed guides 14-, which are adapted to engage recesses-15, formedin the ends ofi'a brush or broom 16,. which isarranged between: said extensions 4-. Bythis arrangement the brush l6 is-adapted tohave avertical sliding movement-between said eXtensions-. Coilsprings 1-7= are arrangedupon the top of the box or casing 1, one endofsaid springs being: connected to the-top of the brush 16, whereby the same is normally lifted and held in a raised position out of engagement With the surfaces on which the sweeper is resting. Suitable stops 18, which are secured to the guides 14, are arranged to prevent the brush from being lifted too high by the springs 17. Pivotally connected to the top of the brush 16, by means of apertured lugs 19, is a handle-bail 20, having arranged thereon a socket to receive a handle 21, by which the machine is pushed.

When the machine is pushed forwardly by the handle 21, the brush 16 will be forced downwardly into engagement with the carpet or surface being swept, which will brush or sweep the dirt ahead, where it will be taken up by the rotary brush 8 and deposited into the pan 7, thus thoroughly cleaning the surfaces over which the machine is being passed. As soon as the machine is sto pod and the pressure removed from the ban le 21 the spring 17 will lift the brush from said surface, so that the machine may be readily drawn backward.

From the foregoing description, taken in connection with the accompanying drawings,

the construction and operation of the invention will be readily understood without re quiring a more extended explanation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I i 1. In a carpet-sweeper, the combination with a wheeled box or casing, of a dustan arranged therein, a rotary brush revolu ly mounted in said casing, means whereby said brush is revolved, a non-rotary brush carried by said casing, guides arranged on said casing to engage guideways or recesses formed in said. brush whereby the same has a vertical sliding connection with said casing, springs connected to said casing and to said brush whereby the latter will be lifted and held in an inoperative position, and a handle pivotally connected with said brush whereby the same is forced downwardly into working position and whereby the machine is pushed along, substantially as described.

2. In a carpet-sweeper, the combination with a box or casing having front supportingwheels and rear su porting-rollers, of a rotary brush mounted therein, friction-wheels arranged on the shaft of said brush to be engaged by said front supporting-wheels and thereby revolve said brush, fly-wheels arranged on the shaft of the latter, a non-rotary brush, means whereby the same is slidably mounted in said casing, springs to normally elevate said brush, stops to limit the upward movement of the same, and a handle pivotally connected to the brush whereby the latter is forced to a workin position and the machine pushed along, substantially as described.

3. In a carpet-sweeper, the combination -with a box or casing, having front, driving and supporting wh'eels and rear su portingrollers, of a rotary brush journale therein,

' and held up in an inoperative position, and a handle connected to said brush whereby the latter is forced downwardly to a'working osition and the machine pushed forwardl substantially as described. a

4. In a carpet-sweeper, the combination with a-boX or casing having front driving and supporting wheels and rear supporting-rollers, of a=rotary brush revolubly mounted in said casing, friction-wheels and fly-wheels mounted on the shaft-of said rotary brush, a bar or stra having bearings for the shafts of said front rive-wheels and said rotary brush, the bearings of said drive-wheels being elon gated, whereby the latter are engaged with and disengaged from said friction-wheels, a non-rotary brush slidably mounted in said casing, springs to lift and hold said brush up in an inoperative position, and a handle connected to said brush whereby the latter is forced downwardly to an operative position and the machine ushed forwardly, substantially as described? Intestimony whereof I have hereunto set my hand in presence of two subscribing witnesses. e
